An Iranian Christian has been forced to return to prison before her medical treatment could be completed, reports Mohabat News.

Maryam Naghash Zargaran, 36, a convert to Christianity, is a little over halfway through a four-year sentence for “gathering [information], collusion and action against national security”.

Zargaran underwent heart surgery nine years ago and needs regular medical check-ups. She has also been diagnosed with lumbar disc disease, arthritis and osteoporosis.

Initially she was denied medical leave, but it was eventually granted on 27 October, only for her to be forced to return to prison before her treatment could be completed.
